(See note 2.)
(1 s max.)
Press the Left Key (front panel: DATA Key for less than
1 s) or Right Key to display the analog monitor output 1
(AM) offset amount. (See note 3.)

4-11-7 Servomotor Current Detection Offset Adjustment
• Servomotor current detection offset adjustment has already been completed at the factory. Conse-
quently, there is normally no need to perform adjustments.
• If you think that the torque ripple caused by current detection offset is abnormally large, perform Ser-
vomotor current detection offset automatic adjustment (Fn00E).
• After performing automatic adjustment, perform manual adjustment (Fn00F) if you still want to lower
the torque ripple even further. If manual adjustment is performed badly, however, there is a risk of
worsening the characteristics.
H Servomotor Current Detection Offset Automatic Adjustment (Fn00E)
• Perform automatic adjustment to the Servomotor current detection offset.
